Question: 1 / 400

Changes in direction of groups of enamel prisms:

Increase enamel strength

Are indicative of underlying pathology

Have no functional importance

The fact that changes in direction of groups of enamel prisms have no functional importance is supported by studies that have shown no difference in enamel strength with these changes. Options A and D are incorrect because they claim the changes increase enamel strength and facilitate enamel repair, respectively, but there is no evidence to support these claims. Option B is also incorrect because changes in direction of groups of enamel prisms can occur naturally and do not always indicate underlying pathology.
